Detailed Description
The utility model will be further described with reference to the accompanying drawings.
The utility model provides a ventilation framed panel structure of motor as described in figures 1 to 5, includes motor 1 and support framed panel 2, has seted up the mounting hole 3 with motor 1 looks adaptation on the support framed panel 2, the outside of motor 1 is provided with a plurality of supporting ribs 4, and the edge of mounting hole 3 is provided with the supporting groove 5 with supporting rib 4 matched with, motor 1 passes through supporting rib 4 and installs on the mounting hole 3 of support framed panel 2 with the cooperation of supporting groove 5.
In the prior art, as shown in fig. 1 and 2, a stator core part of a motor 1 is mounted on a supporting frame plate 2, the outer surface of the motor 1 is spaced from a gap between a mounting hole 3, when the outlet air of a cooling fan blows to the motor 1, air flow is difficult to flow through the gap between the motor 1 and the mounting hole 3, so that the ventilation effect is poor, and the temperature of the motor 1 is high during operation.
In the present utility model, as shown in fig. 3 and 4, a ventilation slot 6 is disposed between two adjacent support slots 5, and the support frame plate 2 is spaced apart from the motor 1 at the ventilation slot 6 to form an air passage 7, and cooling air flow can flow through the air passage 7, so as to improve the axial ventilation effect of the motor 1, make the cooling air flow better take away the heat of the motor 1, and improve the heat dissipation effect when the motor 1 operates.
The ventilation groove 6 is internally provided with an air guide chute 8, and the air guide chute 8 deflects towards the adjacent support groove 5 along the extending direction of the air passage 7, so that the air flow passing through the air guide chute 8 flows to the support rib 4 of the motor 1. The corresponding position of the supporting plate frame and the supporting ribs 4 can block air flow, so after the air flow passes through the supporting frame plate 2, the cooling effect of the air flow on the supporting ribs 4 on the motor 1 is poor, and therefore the air guide chute 8 is arranged, so that the flow direction of the air flow passing through the air guide chute 8 is changed and flows to the supporting ribs 4, the air flow distribution is more uniform, and the overall cooling effect of the motor 1 is better.
As shown in fig. 5, two air guiding chute 8 are disposed in a single air guiding slot 6, the two air guiding chute 8 are respectively disposed at two sides of the air guiding slot 6, and the two air guiding chute 8 are respectively deflected towards the supporting slots 5 at two sides of the air guiding slot 6, so that the air flow passing through the air passing channel 7 is directed to the supporting ribs 4 at two sides, and the air flow distribution is more uniform.
As shown in fig. 5, the air guiding chute 8 is located on the side of the ventilation slot 6 opposite to the motor 1, and the depth of the air guiding chute 8 gradually decreases along the extending direction of the air passage 7, so that the air flow passing through the air guiding chute 8 has a tendency to flow to the surface of the motor 1, and the heat dissipation effect of the air flow on the motor 1 is improved.
Specifically, the mounting hole 3 is a circular hole, the ventilation groove 6 is a fan-shaped groove, the circular arc groove bottom 9 is arranged on the ventilation groove 6, and the circular arc groove bottom 9 and the mounting hole 3 are concentrically arranged. The air guiding chute 8 is correspondingly arranged on the circular arc groove bottom 9, so that the air guiding chute 8 is positioned on the side, opposite to the motor 1, of the ventilation groove 6.
When the motor cooling device works, the motor 1 arranged on the supporting frame plate 2 runs at a high speed, the cooling fan blows air to the motor 1, and the ventilation groove 6 is formed in the mounting hole 3 of the supporting frame plate 2, so that air flow blown by the cooling fan can pass through the supporting frame plate 2 along the axial direction of the motor 1, and the heat dissipation effect of the motor 1 is further improved; the air guiding chute 8 can enable part of air flow to deviate after passing through the air passage 7, so that the air flow is more uniform, and the heat dissipation effect of the motor 1 is further improved.
